Figure 1: Transpulmonary thermodilution curve analysis. Global end-diastolic volume derived from PiCCO system depends on mean transit time, the time required for half of indicator to pass thermistor in femoral artery catheter and downslope time, time of the temperature decay between two set points of dilution curve. In contrast, global end-diastolic volume from volume view system depends on maximum upslope (S1) and maximum downslope (S2) of dilution curve. GEDV: Global end-diastolic volume, Mtt: Mean transit time, Dst: Downslope time
